2D Lanthanide-Directed Architectures on Surfaces

Seminář / Út, 04/04/2017 - 10:00 - 11:00

David Ecija (IMDEA Nanoscience, Madrid, Spain; Email:david [dot] ecijaatimdea [dot] org | Web site: http://ecija.hol.es)

Metallosupramolecular engineering on surfaces provides a powerful strategy toward surface-confined coordination architectures with prospects for several application fields. To date most efforts concentrated on incorporating transition metals, and only recently we pioneered lanthanide-directed assembly.

Defects and magnetic structure of CuMnSb

Seminář / Út, 04/04/2017 - 15:00 - 16:00

František Máca (Department of Condensed Matter Theory, FZÚ AV ČR, v.v.i.)

Abstract: Total energy calculations show that the antiferromagnetic (111) order is not the ground state for the ideal CuMnSb in contrast to the results of neutron diffraction experiments. The magnetic phases of the CuMnSb were investigated with the aim to clarify the role of defects which exist in real samples (Mn-antisites on Cu, Mn-interstitials, and Cu-Mn swaps) of spintronic Heusler alloys. The full-potential supercell approach and the Heisenberg model were used to find the magnetic structure of the CuMnSb with defects.

Helical Molecules and Surfaces: Self-Assembly, Spin Filtering and Unidirectional Motors

Seminář / Čt, 06/04/2017 - 10:00 - 11:00

Karl-Heinz Ernst (Empa, Swiss Federal Laboratories for Materials Research and Technology Department of Chemistry, University of Zurich )

The Nobel Prize for Chemistry 2016 is shared by Jean-Pierre Sauvage, J. Fraser Stoddard and Ben Feringa for the development of molecular machines. The three researchers designed molecules with subunits that moved relative to each other in a controlled manner, and therefore founded a new field in chemistry. Some of their molecules can, for example under influence of light, even fulfill work. The three laid the foundation for nanoscopic motors, like molecular escalators, molecular muscles and nanocars.
